Did you know that less than 5% of the world’s population has the ability to lick their own elbow?

Bart devours everything from the Guinness Book of World Records to Weird But True, to Bart’s King-Sized Book of Fun, and everything in between, and usually at the breakfast/lunch/dinner table. Today’s math minute was inspired by an animal featured in the National Geographic Almanac 2010.
Meet Tylosaur, a vicious prehistoric marine dinosaur with two rows of teeth and body length up to 29 feet. 29 feet long? Just how long is that?  Well, get out your tape measure and see for yourself!

By the way, did you know that astronauts can’t whistle on the moon? π
